Title: Oxygen enricher
Inventor: ICHIKAWA KOJI
IPC: B01D53/04
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To improve both the durability and the oxygen concentration in a product gas without causing a remarkable mechanical change in a pressure swing adsorption type oxygen enricher by making an oxygen-enriched gas flow from a surge tank to an adsorption bed when a specific pressure swing width attains in a desorbing step for the adsorption bed filled with an adsorbent. SOLUTION: An adsorption bed 8 filled with an adsorbent for preferentially adsorbing nitrogen to oxygen is arranged in the interior of an adsorption column 1. Air is then fed from a changeover valve 4 through a compressor 5 into the adsorption column 1 to adsorb the nitrogen. The resultant oxygen-enriched gas is then discharged through conduits 3 and 23 equipped with automatic closing and opening means 2 and 22 and a surge tank 9. When the pressure variation width of the adsorption bed 8 attains <=10%, the oxygen-enriched gas is made to flow from the surge tank 9 through the conduits 3 and 23 to the adsorption bed 8. The nitrogen adsorbed on the adsorption bed 8 is then desorbed and discharged through the compressor 5 and the changeover valve 4.

Title: Digital recording and reproducing device
Inventor: GYOTOKU TAICHI
IPC: H04N19/134
Filed: 1993-01-11
Abstract: PURPOSE:To obtain the digital recording and reproducing device in which a value used for discriminating picture changeover is relaxed by selecting a spe cific picture depending on a count of a block number to be corrected. CONSTITUTION:A correction flag memory control circuit 13 detects a SYNC block to be corrected based on information of an inner flag memory 5 and an outer flag memory 8, and outputs a corresponding address to a correction flag memory 12, in which a level 1 is written. Simultaneously a counter 14 counts number of SYNC blocks to be corrected. When the count of the counter 14 reaches a count or over in a prescribed time, a decoder 15 detects it and outputs a signal to select a specific picture. Thus, a value used for discriminating picture changeover is relaxed by counting number of blocks to be corrected and selecting a specific picture based on the count forcibly.

Title: Optical recording and reading method
Inventor: UENO TOSHIHIKO
IPC: G11B7/24035
Filed: 1986-01-09
Abstract: PURPOSE:To produce a recording medium conveniently and at a low cost and to realize high S/N by using a cholesteric liq. crystal as a recording medium by equalizing the rotating direction of the circularly polarized light beam for reading with the spirally rotating direction of the cholesteric high molecular liq. crystal. CONSTITUTION:A light absorbing layer 2 and a cholesteric high molecular liq. crystal thin film 3 are successively formed on a substrate 1. Light is selectively reflected by the high molecular liq. crystal with the wavelength shown by lambda=np of the counterclockwise circularly polarized light as the center. When the pitch p is previously controlled to conform almost to lambda-np against the wavelength of the reading light source, extremely high reflectance is exhibited at a region wherein information is not written, meanwhile, the reflectance is rapidly decreased at the region wherein information is written in the mode to form a pit, and consequently high S/N can be realized. Besides, when the pitch p is previously controlled to lambda>>np against the wavelength of the reading light source and information is written in the light quantity region to increase the pitch length, extremely low reflectance is obtained in the unwritten part of information, high reflectance is obtained in the written part, and high S/N is similarly realized.

Abstract: PROBLEM TO BE SOLVED: To select only a glossy part for display by determing and processing the glossy part and a unglossy part on the basis of picture element information provided by processing a signal from an image pick-up camera. SOLUTION: A frame memory 22 stores a red signal R, a green signal G, and a blue signal B from a solid image pick-up camera 21. By means of an HLS converting unit 32, RGB output information from the camera 21 is converted into respective image data of hue, chromaticness, and lightness so as to be stored. By means of a glossy part selecting unit 4, it is determined whether a relationship between chromaticness and lightness of a picture element outputted from the HLS converting unit 32 satisfies a certain formula or not, and consequently it is determined whether it is a glossy part or a unglossy part, and then, an address signal for the picture element is outputted to a glossy part extracting unit 6. By means of the extracting unit 6, the address signals are accumulated, and the RGB signal corresponding to the address is extracted from the frame memory 22.  The extracting RGB signal is transferred to a display memory 7 so as to be displayed in the display unit 8. An address for the unglossy part is prevented from extracting the RGB signal.
